Bought the extension battery for my VTOMAN flashspeed 1500. Very happy with double the capacity, and it works perfectly so far. VTOMAN creates quality products; I've had the Flashspeed for 3 years of daily use and have had no issues. Read more

I am a newbie when it comes to power stations. As often happens to newbies, my first purchase was a poor choice. The color Orange does not make a product better suited for emergencies or a better product. It may make you feel that way but, in the end it's the features and quality that makes a difference. I found that quality in the VTOMAN JUMP 600X. I was even more excited when I found out about the auxiliary 640Wh battery. It more than triples your power reserve and that in not a bad thing. One nice thing is you do not always have to carry around a super heavy power station. The Jump 600X is lightweight, if you need more reserve, you bring the battery along. Mine came 75% charged, hooking it to the power station is done with one simple cable. It charges through the power station. Very easy to do. At least once a year the transformer on the next block goes out with a bang and were without power for at least 8 hours. If you have teenagers in your home, they panic when they can't charge their phones, laptops, chrome books, whatever. Also, it just enough time for things in the fridge and freezer to start to go bad. I believe this will solve both those problems and my son can be use it for his camping trips. The units are nice looking and will not look out of place in your home, the fit and finish perfect. The yellow accents don't scream at you like Orange does. Some videos I watched pointed out being able to stack these would have been a benefit. This can easily be accomplished using the foam pad from the battery box. It straddles the handle on the power station and supports the battery. Or you can use it in the reverse order with the power station on top. I don't know why no one figured that out. Buying these two was a no brainer for me. 600 watts, LIFEPO4 batteries, 939Wh of power. Two separate units are easier to carry than one really heavy one. The Gray and Yellow is pleasing to the eye if that matters to you. If you notice, the 12-volt socket has a cigarette lighter plug in it. I purchased it from amazon for $1.49. I will keep dirt and foreign objects out. Buying these two is a bargain. Compared to some other offerings of similar power and features I would choose these two every time. Read more

While recharging my Vtoman overnight I awoke to what I thought was a defective battery; it appeared not to be progressing in its charging. I was upset and thought my battery was not properly functioning. The main battery charged fully, but the auxiliary appeared “dead”. I was mistaken. The battery needed more time to charge than I expected. I overreacted and, without consideration, wrote a scathing review. The customer service team got back to me and resolved my problem. I watched a YouTube video about the issue and determined I was wrong in my assessment. I was in the process of rewriting my review when my pad died and rather than starting over again I decided to “let it go”. That was a disservice to the company. I enjoy the product and use it regularly. My wife uses the main battery almost daily as an auxiliary power source for small appliances used on our kitchen “island”. A small cart holding the battery is rolled next to it and works great. No rewiring needed, very convenient. The extra battery is always waiting for emergency use should there be a power outage, the reason for my purchase of these batteries. Vtoman, please accept my apology for this overdue amendment.

I ordered this extra battery to go with my VTO Man 1500. With them in concert this thing is very very strong I have not been able to use it long-term yet so I can't say about that but I do know that it puts out very good it's got real high voltage I amperage high wattage it is all I wanted. I have four of these things this one is by far the best one I have ordered yet! What order again Read more

I purchased this to add to my previously purchased power bank that I really love! I would give it 5 stars, but, and it's my fault for assuming, that it can only be used WITH it connected to my Jump 1800 and not by itself as it has no output plugs of any kind. Just the port that connects it to the main bank. But, it doubles my stored power so if I need power to run most things I need (and power here goes out frequently) I will now have it. You also cannot charge it without it being connected to main bank either. But all around, I'm glad I purchased it. Read more
